Both Tubes
Both Tubes is an Achievement in Halo 3: ODST. It is unlocked when the player gets 10 kills with a Rocket Launcher during the Kizingo Boulevard Mission. It is worth 5 Gamerpoints.[1]
It is represented by a red and silver signpost with a Rocket Launcher in front of it.
Trivia
- An easy way to do this is to either play co-op, or if you are playing solo, trade your rocket launcher with a marine, and have him ride your Scorpion. His kills will be registered as yours.
- Another way is at the beginning of the level, behind the empty scorpion there is a crate. Behind the crate is a rocket launcher with four more rockets. This still means you must get multiple kills with each rocket though.
- There are also two marines toting rockets on a building in the first courtyard. They'll come down if you are driving a vehicle, and you can kill them for extra ammo. If you don't mind that sort of thing.
- When you get to the point in the level where there is a arrow over your treammate Dutch, there is a rocket launcher with four rockets on top of the building where you find the broken guass turret clue.
- If you find the two drops there is a total of ten rockets altogether in the level so you only need to get one kill with each.
